A New Orleans resident challenges out-of-towners who had come to protest against the 2017 removal of the Robert E. Lee Monument. The out-of-towners' inability to pronounce "Tchoupitoulas Street" according to the local fashion would be a shibboleth marking them as outsiders.
A shibboleth (/ˈʃɪbəlɛθ,-ɪθ/ⓘ;[1][2]Hebrew: שִׁבֹּלֶת, romanized: šībbōleṯ) is any custom or tradition, usually a choice of phrasing or single word, that distinguishes one group of people from another.[3][2][4] Historically, shibboleths have been used as passwords, ways of self-identification, signals of loyalty and affinity, ways of maintaining traditional segregation, or protection from threats. It has also come to mean a moral formula held tenaciously and unreflectingly, or a taboo.[5]
